Exhaust Ventilation System
An exhaust ventilation system, also known as an exhaust system or exhaust fan system, is a type of ventilation system designed to remove contaminated air, odors, fumes, moisture, and pollutants from indoor spaces and expel them outdoors. These systems are commonly used in residential, commercial, industrial, and institutional buildings to improve indoor air quality, control humidity levels, and create a more comfortable and healthy environment.
Exhaust Fans : The primary component of an exhaust ventilation system is the exhaust fan, which is responsible for drawing air out of the building and expelling it outdoors. Exhaust fans may be installed in various locations, such as bathrooms, kitchens, utility rooms, laboratories, manufacturing facilities, and other areas where air contaminants are generated.
Ductwork : Exhaust fans are connected to ductwork, which distributes the air from the exhaust fan to the exterior of the building. Ductwork may consist of metal or flexible ducts, depending on the specific requirements of the application. Properly sized and installed ductwork ensures efficient airflow and prevents the buildup of contaminants within the building.
Exhaust Vents : Exhaust vents or outlets are installed on the exterior of the building to discharge the contaminated air expelled by the exhaust fans. These vents may be located on the roof, walls, or soffits, depending on the building's design and local building codes.
Controls and Monitoring : Modern exhaust ventilation systems may include controls and monitoring devices to regulate fan speed, activate fans based on occupancy or activity levels, and provide alerts for maintenance and safety issues. Programmable timers, motion sensors, and humidity sensors are commonly used to automate the operation of exhaust fans.
